Product details
Granite flat ruler
Usage: Mainly used for measuring the flatness and straightness of machine tool worktables, guide rails and precision working surfaces.
The material of the granite ruler is: Jinan green, black gloss, precise structure, uniform texture, good stability, high strength and high hardness. It is a precision reference measurement tool made of natural stone materials. It is an ideal reference surface for the inspection of instruments, precision tools, and mechanical parts, especially for high-precision measurements.
Granite flat ruler
Made from high-quality underground rock layers, after hundreds of millions of years of natural aging, its shape is extremely stable, so there is no need to worry about deformation due to regular temperature differences. Granite ruler is a granite material that has undergone strict physical testing and selection. It has fine crystallization and hard texture. Since granite is a non-metallic material, it has no magnetic reaction and no plastic deformation. It has high hardness and therefore good accuracy retention. Even if the rock tool is bumped by heavy objects during use, at most a few grains of stone will fall off. Granite ruler is superior to precision measurement reference parts made of high-quality cast iron and steel, and can achieve high and stable accuracy.
Characteristics and advantages of granite flat ruler:
After long-term natural aging of the rock, the structure is uniform, the expansion coefficient is extremely small, the internal stress completely disappears, and it does not deform, so it has high accuracy.
, good rigidity, high hardness and strong wear resistance.
, not afraid of acid and alkaline liquid corrosion, will not rust, does not need to be oiled, is not easy to stick to dust, is easy to maintain, and has a long service life.
There will be no scratches, it will not be blocked by constant temperature conditions, and the temperature measurement accuracy can be maintained at room temperature.
, non-magnetized, can move smoothly during measurement, has no sluggish feeling, is not affected by moisture, and has good flatness.
